TDA38813 - 12A synchronous Buck regulator

Datasheet Summary

Description

The TDA38813 is a 12 A fully integrated and highly efficient dc - dc Buck regulator.

It uses a fast Constant On-Time (COT) control scheme, which simplifies the design efforts and achieves fast transient response while maintaining excellent line and load regulation.

Features

  • Wide Input Voltage Range: 4 V to 16 V with internal bias and 2.7 V to 16 V with external VCC (3.3 V).
  • Precision Reference Voltage (0.9 V +/- 0.5%).
  • Stable with Ceramic Output Capacitors.
  • No External Compensation.
  • Optional Forced Continuous Conduction Mode and Diode Emulation for Enhanced Light Load Efficiency.
  • Selectable Switching Frequency from 600 kHz, 800 kHz, and 1 MHz.
  • Programmable Soft-Start Time with a minimum of 1.5 ms & Enhanced Pre-Bias Start-Up.
